Here’s a shot of a lock destroyed by snapping. Not the usual, it came off an aluminium door, and this photo shows the way the lock case has pretty much exploded under the force of the attack.
The ‘locksmith’ who did this should be prosecuted. They left the two locks on the door broken! This one was totally inoperable, the other one throws the bolt about 10mm out the lock, and it can be pushed back trivially, and so the door could be opened with barely any force or effort, despite appearing secured.
Further, after snapping the cylinders, they were replaced by a pair of massively over-sized cylinders that stuck out over 30mm on each side of the door!
Whether you are a locksmith or not, you should not be snapping locks without great care. (Also, you will start running into anti-snap locks. Because us good locksmiths fit them!)
